Hybrid Digital-Analog Approximate Inverse Preconditioning for Krylov Methods
Shikhar Shah, Rui Peng Li, Tayfun Gokmen +3
Analog in-memory computing enables highly parallel matrix-vector multiplications with reduced data movement, but the resulting operations are noisy, quantized, and affected by devi…

Generative modeling of granular flow on inclined planes using conditional flow matching
Xuyang Li, Rui Li, Teng Man +1
Granular flows govern many natural and industrial processes, yet their interior kinematics and mechanics remain largely unobservable, as experiments access only boundaries or free…

Neural Approximate Inverse Preconditioners
Tianshi Xu, Rui Peng Li, Yuanzhe Xi
In this paper, we propose a data-driven framework for constructing efficient approximate inverse preconditioners for elliptic partial differential equations (PDEs) by learning the…
